Chasing Diagnostic Errors in the Performance Analytics Admin Console

[Bobby Flake]

We have been on ServiceNow for just over 1 year.  I've recently discovered Admin Console / Trouble Shoot / Diagnostic Errors.

I am attempting to chase down "Dashboard tab does not have a valid reference in the Page field." errors but I can't seem to figure out which dashboard these tabs are on.  There doesn't seem to be any reference to the dashboard in the row or problem record.

How do I identify the dashboard with the issue?

Hello,

We ended up opening a HI ticket to get help with this situation.  The KBA listed in the original solution seemed to be specific to certain dashboards that we didn't have.  We asked them why it might have happened and how to fix the  broken tabs.

The response from ServiceNow is that the tabs could have gotten corrupted when someone tried to move a dashboard via an update set and didn't do it correctly.  The other possibility was that cloning might have caused it.

The ServiceNow team provided some XML to fix a few out of the box dashboards that had the problem.  For any custom dashboards, i.e. dashboards created by our users, they told us to rebuild the dashboard or the tab.  We recreated the broken tabs by going to the dashboards they were on, creating a new tab and then adding all of the same reports, widgets, and filters to it.  Once the new tab looked the same as the old tab, we deleted the old (broken) one.  You can determine which dashboard the tab is on by looking at the 'pa_m2m_dashboard_tabs' table.

Here's the list report that I used to find the dashboards associated our broken tabs:

https://<your instance>.service-now.com/now/nav/ui/classic/params/target/pa_m2m_dashboard_tabs_list.do%3Fsysparm_query%3Dtab.page.sys_idISEMPTY%255EGROUPBYdashboard%26sysparm_first_row%3D1%26sysparm_view%3D

I certainly hope this information saves someone time in the future.
